Is anyone out there with the 69 Dart this belongs to?

I know this is a long shot, but I am looking for the original 340 from my car.

V.I.N.# LM23P9B331109

If anyone has it in their parts hoard, and is willing to part with it, please contact me. Even if it's in your car, I'm willing to trade for a replacement of equal or greater value.
